  • Notes 
    • From Leo van de Pas's site:

      Theodoros distinguished himself during the siege of Constantinople by the crusaders of the Fourth Crusade in 1203-04. After the sack of the city he established himself in the town of Nicaea that became the rallying point for the Byzantines.

      Theodoros formed a new Byzantine state in Asia Minor and in 1206 assumed the title of emperor. His state was besieged by his enemies, but he fought successful defensive campaigns against the Latin emperor of Constantinople Henri of Flanders. He defeated his rival Alexius I, emperor of Trebizond, and successfully attacked Kay Khusrau I, the sultan of Rüm (Iconium or Konya). Theodore's most important victory was gained in 1210 when he captured Alexius and the city of Antioch.

      He had five children by his first wife Anna Komnene Angelina, who died in 1212. Two daughters would have progeny. He next married Philippa of Armenia, but this marriage was annulled after one year on religious grounds. Their son Konstantinos had no rights to the throne, instead becoming duke of Thrakesion. In 1219 he married Marie de Courtenay .

      By the time of his death in August 1222 Theodoros had ruled over a territory covering the old Roman provinces of Asia and Bithynia. By his courage and military skill he enabled the Byzantine nation not only to survive, but ultimately to defeat the Latin invaders.
